ui: Provide deterministic order to task list

[inahga]

Sort tasks by name, with respect to the system's locale.

n.b. it's suggested to use Intl.Collator for large arrays of strings https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare, but it's not specified what "large" entails. I don't currently expect the task list to approach anything that constitutes "large", i.e. no more than 1000 tasks, so I will YAGNI this.

This seems appropriate to me: to handle large numbers of tasks, we'll likely need to add pagination support, so assuming that the number of tasks is small for now makes sense -- I suppose pagination support would require server-side sorting.
